P { margin-bottom: 0.08in; } do tiles crack by themselves in time? A roofing manager's team of drillers, claims our non cracked tiles were already cracked, and were caused by the passage of time and was not caused by their drilling the roof which resulted in continuous raining down of stones, large and small. The cracks in some of the tiles run straight down 2 or 3 tiles in a fine straight line. Does spontaneous time induced cracking of tiles like that appear?
Also for windows, our windows were next to immaculate being wiped weekly, but it is obvious theyre scratched along with the metal frame after the drilling of the roof. Question is why does it appear some of the fine scratches which were not there before the drilling appear to be behind the window of our top floor flat, detected by using finger nail scrapes for a slight indent ?
